1. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?
- A. Refer her for an exploratory laparotomy
- B. Measure serum gastrin in response to secretin infusion
- C. Treat her for H. pylori
- D. Obtain a dedicated small bowel series
Correct answer: B
Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.
2. A healthcare professional is assessing a client who has been taking digoxin. Which of the following findings should the healthcare professional report to the provider?
- A. Weight gain
- B. Dry cough
- C. Hypokalemia
- D. Bradycardia
Correct answer: D
Rationale: The correct answer is D: Bradycardia. Bradycardia is a significant finding associated with digoxin toxicity. Digoxin, a medication commonly used to treat heart conditions, can lead to bradycardia as a sign of toxicity. Bradycardia requires immediate attention and reporting to the healthcare provider for further evaluation and management to prevent serious complications. Choices A, B, and C are incorrect because weight gain, dry cough, and hypokalemia are not specific signs of digoxin toxicity. While weight gain can be a side effect of digoxin, it is not a classic sign of toxicity. Dry cough is more commonly associated with medications like ACE inhibitors, and hypokalemia can be a complication of digoxin therapy but is not a direct sign of toxicity.
3. A nurse is delegating the collection of a sputum specimen to an assistive personnel (AP). At which of the following times should the nurse instruct the AP to collect the specimen?
- A. In the afternoon
- B. As soon as the client awakens in the morning
- C. Before bedtime
- D. Immediately after lunch
Correct answer: B
Rationale: The correct answer is B: 'As soon as the client awakens in the morning.' Sputum specimens should be collected early in the morning to obtain a concentrated sample. This timing ensures that the specimen is less diluted, providing a more accurate analysis. Choices A, C, and D are incorrect as they do not align with the optimal timing for collecting a sputum specimen, which is in the morning.
4. What is the function of chylomicrons?
- A. Produced in the hepatic system.
- B. Composed of triglycerides and cholesterol only.
- C. Absorbed in the large intestine.
- D. Cleared from the blood by lipoprotein lipase.
Correct answer: D
Rationale: Chylomicrons are particles that transport dietary fats from the small intestine to cells in the body. They are cleared from the bloodstream by lipoprotein lipase, an enzyme that breaks down triglycerides in chylomicrons into fatty acids and glycerol. This process allows fats to be absorbed by the body. Choices A, B, and C are incorrect because chylomicrons are not formed in the hepatic system, they are composed of various lipids including triglycerides and cholesterol, and they are absorbed in the small intestine, not the large intestine.
5. In educating the parents of a child diagnosed with hypothyroidism, the nurse mentions that the child should avoid goitrogens. Which of the following will the nurse mention as an example?
- A. Orange
- B. Tomatoes
- C. Cabbage
- D. Grapes
Correct answer: C
Rationale: Cabbage is an example of a goitrogen that should be avoided in children with hypothyroidism. Goitrogens are substances that can interfere with thyroid function by inhibiting iodine uptake, potentially worsening the condition. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contains compounds that can affect thyroid hormone production. Oranges, tomatoes, and grapes are not classified as goitrogens. Therefore, it is important for parents to be aware of foods like cabbage and to limit their child's intake to help manage their hypothyroidism effectively.
